1 Claim. (Cl. 301-35) This invention relates to wheels for use withpneumatic tires, particularly to heavy duty wheels although it will beapparent from the following description that many features of theinvention are equally well adapted to a wide variety of wheel structuresand types.

An object of this invention is to provide an improved wheel constructionfor heavy duty purposes.

A further object is to provide a wheel having an improved constructionand arrangement for mounting a divided rim on a supporting flange, thelatter preferably being formed as an integral part of the wheel hub.

Aiurtheraobject is to provide a wheel structure having a divided rim inwhich the fastening means used in connecting the separable rim partstogether is employed to augment the driving connection between the rimand the associated bolting-on flange.

These and other objects which will be apparent are accomplished by theinvention hereinafter described and illustrated in the accompanyingdrawing in which:

Fig. 1 is a view in elevation of a wheel constructed in accordance withone embodiment of this invention,

Fig. 2 is a section on the line 2-2 of Fig. 1,

Fig. 3 is a section on the line 3-3 of Fig. 1,

Fig. 4 is a section on the line 4-4 of Fig. 3,

Figs. 5 and 6 are sections on the lines 5-5 and 6-6 of Fig. 1.

The illustrated embodiment of the invention comprises a hub ll havingspaced outboard and inboard bearing seats l2 and I3, respectively,

and an inboard radial flange l4 for mounting a brake drum, not shown.The hub is formed with outwardly extending, converging walls and I6extending angularly outward from the bearing seats 12 and 13,respectively, to form a strong support for an annular bolting-on flangeH in which are mounted a series of rim supporting studs'l8 secured inthe flange in any conventional manner. A divided rim includes a rimsection l9 having an axially extending surface 2| terminating in a tireretaining flange 22 at one edge and a depressed seat :23 at the otheredge which is also provided with a radial securing flange 24. Acooperating rim section 25 has a bead supporting surface 26 engaging theseat 23, and a radial securing flange 26. The two rim sections aremounted on the studs 3 and secured in place by ball nuts and washers 21.

The separable parts l9 and 25 of the divided rim are also independentlysecured together to permit dis'mounting thereof as a unit from thebolting-on flange. For this purpose relatively short rim clamping studs3| are secured in the radial flange 24 of the inboard'rim member I9,

and the radial securing flange 26' of the outboard rim member is mountedthereon and secured thereto by ball nuts and washers 32. The heads 33 ofthe short rim-securing bolts 3! have flattened faces 34 and 35, see Fig.4, which engage the edges of an annular recess 36 formed in the innerface of the securing flange 24 of the inboard ri-m member l9, for thepurpose of holding the stud in the flange against turning.

The bolt heads .33 are of substantial size and, when the rim is mountedon the bolting-on flange l1 these heads project into openings orrecesses 31 formed in the outboard face of the bolting-on flange H, seeFig. 3. This augments the driving connection between the flange and therim provided by the conventional bolting-on studs 18. The recess 31 isdeeper than the projecting portion of the bolt heads 33 to insureclamping engagement between the bolting-on Y flange and the inner faceof the rim securing flange 24, and is of circular contour asindicated indotted lines in Fig. 4, the diameter of the recess being sufficient toaccommodate manufacturing tolerances in the center spacing of the studs3|. In the illustrated embodiment one out of every four studs employedis a short stud 3|, the remaining studs being the conventional clampingstuds I 8.

As shown in Figs. 1 and 5, a plurality of jack screws}! are provided.These screws extend loosely through openings 42 in the outerrim-securing flange 26 and are threaded through the inner rim-securingflange 24 so as to bear on the adjacent face of the bolting-on flange I!to provide means for forcing the rim off the bolting on flange, whennecessary.

In Fig. 6 is shown the valve stem arrangement in which an angularlyextending valve stem 44 extends outwardly through a slot 45 in the rimsection l9, and through a resilient doughnut shaped gasket 46 mounted inan opening in the securing flange 26 of the outer rim member 25.

' Although we have described a specific embodiment of this invention isdetail, it will be apparent that the invention can be variously modifiedand adapted within the scope of the appended claim.
